+SB.PCI0.SMB0 device drivers unavailable
+
+QEMU 4.2 introduces new device with this code:
+
+static void build_smb0(Aml *table, I2CBus *smbus, int devnr, int func)
+{
+    Aml *scope = aml_scope("_SB.PCI0");
+    Aml *dev = aml_device("SMB0");
+
+    aml_append(dev, aml_name_decl("_HID", aml_eisaid("APP0005")));
+    aml_append(dev, aml_name_decl("_ADR", aml_int(devnr << 16 | func)));
+    build_acpi_ipmi_devices(dev, BUS(smbus), "\\_SB.PCI0.SMB0");
+    aml_append(scope, dev);
+    aml_append(table, scope);
+}
+
+It is detected by Windows 10 as 'Unknown Device' and there is no driver available.
+Please provide a working Windows driver or give ability to disable this device.
+
+what is this shit?
+
+I noticed this as well. Apparently it was introduced in the following commit:
+
+https://github.com/qemu/qemu/commit/ebe15582cafeb944a1c6e99aa526e81a1551c567
+
+Saying:
+
+---
+pc: Add an SMB0 ACPI device to q35
+
+This is so I2C devices can be found in the ACPI namespace.  Currently
+that's only IPMI, but devices can be easily added now.
+
+Adding the devices required some PCI information, and the bus itself
+to be added to the PCMachineState structure.
+
+Note that this only works on Q35, the ACPI for PIIX4 is not capable
+of handling an SMBus device.

+
+Any progress? When will you provide a Windows driver for this and/or ability to disable this device in Qemu?
+
+I'm also having this issue on a Win 10 VM running on a unRaid server.

+Hi, although this isn't my area of expertise, the bug caught my eye. Peter Maydell points out that there is a commit that addresses this issue: https://github.com/qemu/qemu/commit/aefcaf9d1b3ebb30981627bd08f595211a648a62
+
+It just never made its way back here to launchpad.
